Power Reset issue

Category: Hardware
Product Number: MAX20008

Dear Team,

We are using MAX20008 buck converter in our circuit.

Purpose is to convert +12vdc to +5vdc using buck converter and then convert to +3.3vdc(Used Linear regulator) to run the mcu

Below is how our circuit looks like

We have also used EE Simulator for building this circuit as well.

Now the issue we are facing is the system resetting. Our main +12vdc source is switching causing since +5vdc output is switching causing the mcu reset.

Please help me to resolve this issue with your guidance.

Please let me know what are the information required to solve this issue like part details, oscilloscope waveform at points

Looking forward for all support.

Thank you
